COPPER TREATING FURNACE Filed June 9, 1931 2. Sheets-Sheet 2 Invcnlor Z- M Desamm" ref Patented May 24, 1932 UNITED STATES PATENT OFFICE WILLIS J. BENSON AND LOUIS M. DESAMAIS, OF DOUGLAS, ARIZONA COPPER TREATING FURNACE Application filed June 9, 1931. Serial No. 543,198.

This invention appertains to new and useful improvements in furnaces for treating copper and other similar metals in molten or other forms in a more efficient and practical manner, than is now possible with the use of conventional apparatus.

An important object of this invention is to provide an apparatus for thoroughly treating copper to remove the impurities thererom.

Another important object of the invention is to provide a metal treating furnace capable of being rocked to a position when being charged to avoid damage to nozzles or other appurtenances in the furnace.

Still another important object ofthe invention is to provide an apparatus for removing impurities from copper at much less cost than is now possible with conventional machinery.

These and other important objects and advantages of the invention will become ap-v parent to the reader of the following specification.

In the drawings Figure 1 represents a side elevational view of the apparatus.

Fig. 2 represents a. longitudinal sectional view through the furnace.

Fig. 3 represents a sectional view taken substantially on the line 33 of Fig. 2.

Fig. 41: represents a cross sectional view taken substantially on the line 4-4 of Fig. 2.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 55 represents a channeled base block within the channel of each, a pair of flanged rollers 66 are mounted in a manner so as to protrude above the blocks to support the cylindrical furnace generally referred to by numeral 7. This furnace 7 includes the cylindrical shell 8 provided with the filler opening 9 therein, and further provided with the end plates 1011 secured to the flanged ends 12 of the shell 8 by bolts 13.

Adjacent each end of the shell 8 is a circumferentially extending rib 14. which is en gaged by the corresponding pair of rollers 66, on the underlying block 5. At the end of the furnace adjacent'the end plate 11 is the ring gear 15 which is meshed with by the pinion 16 on the drive'shaft 17, which drive shaft is secured to a suitable motive device.

The end plate 11 has a packing gland 18 therein through which the hollow shaft 19 ex- 7 tends, and as is clearly shown in Fig. 2, this hollow shaft 19 also extends through the end plate 10 and is journaled in the bearing 20 outside of the furnace 7.

The end of the shaft 19 adjacent the packing gland 18 is connected to the T-fitting 21. A pipe 22 for supplying steam to the conduit 19 is connected to the T-fitting 21 and has a control valve 23 therein. A pipe 24 through the fitting 21 for supplying air to the shaft 19 and has a valve 25 therein for controlling the air supply. v

A multiplicity of spouts 26 extend laterally from the shaft 19 and have right angularly disposed nozzles 27 onthe ends thereof. From these nozzles, the mixed air and steam can discharge into the copper content of the furnace. As is apparent in Fig. 2, the entire furnace is lined with arefractory material 28 to withstand the heat produced by the burner 29, which is preferably of the oil feed type.

It can be seen, that by placing the copper or other material in the furnace, and opening the valves 23 and 25, steam will be admitted to the furnace to contact with the metal and the heat from the burner 29 will suffice to complete the treatment, after which the furnace can be dumped by rotating the shaft 17 which is geared to the furnace shell 8. Air is used to bring back over-steamed copper to normal condition.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described our invention, what we claim as new is 1.- A metal treating apparatus of the character described comprising a cylinder having an opening in the top thereof, said cylinder being horizontally disposed, a hollow shaft upon which the cylinder is swingably mounted, nozzles projecting from the hollow shaft at points within the cylinder, and steam and air pipes, each provided with a valve, connected to the said hollow shaft.

5 2. A metal treating apparatus of the character described comprising a cylinder having an opening in the top thereof, said cylinder being horizontally disposed, a hollow shaft upon which the cylinder is swingably mounted, nozzles projecting from the hollow shaft at points within the cylinder, steam and air pipes, each provided with a valve, connected to the said hollow shaft, and a burner nozzle projecting into the said cylinder at a point above the said hollow shaft.

In testimony whereof we aflix our signatures.
